Hello everybody,
I have been a problem to use client certificates for authentication on IIS6.
I bouth a valid SSL certificate and a valid client certificate. The SSL certificate was configured in the IIS and the root website can be accessed publicly using https protocol.
Above this root web site I have a virtual directory that I need require client certificate authentication, and it was configured for this.
On client machine I have installed the client certificate, but when I try to access the virtual directory using https protocol the IE doesn't open the certificate dialog for me to select what client certificate I want to use and an error page is showed with 403.7 Error - Unauthorized: Access is denied due to invalid credentials.
The Root Certificate Authority of SSL and Client certificate are both installed on server and client machine on Thrusted Root Certificates.
Any idea?
